In 14 Stages T1 and T2 tumors, 11 were correctly identified and 3 were overstaged. In 11 Stage T3 neoplasms, ecMRI was accurate in 7 cases, and the other 4 were understaged. The overall accuracy of ecMRI in 1.0 T was 72% and that was comparable to the reported accuracy of this technique in high-field systems.

On Figure 1A in that article, I believe the annotated vessel is actually the distal anterior tibial artery and its normal continuation, the dorsalis pedis artery, and that the posterior tibial artery can be seen as a faint, straight, interrupted, vertical vessel medial to the upper half of the annotated branch. I suspect rotational or reconstructed lateral views would confirm this.

Magnetic resonance imaging (MRI) has an important role in the diagnosis, staging, and determining the deep extension found in advanced, aggressive forms of plantar fibromatosis, thereby guiding appropriate clinical and surgical management. This case report aims to provide radiologists and clinicians with simple guidelines for the differential diagnosis of the fibroblastic and fibrohistiocytic soft tissue tumors of the foot with the emphasis on the MRI findings.

Patients with FAI typically present with deep, intermittent groin discomfort during or after activities involving repetitive or persistent hip flexion. Symptomatic improvement can be achieved from arthroscopic debridement of unstable cartilage flaps, shaving of cartilage irregularities, and surgical correction of deformity of the femoral head\endash neck junction. Early and correct diagnosis of FAI has paramount importance for appropriate and timely management of the disorder before the development of osteoarthritis. Magnetic resonance (MR) imaging offers a noninvasive means of assessing the degree of damage to cartilage and adjacent labrum and bone and also evaluating the effectiveness of treatment. This article describes the morphologic types of F...

Symptoms are often out of proportion to the initiating event and not limited to a single peripheral nerve. There is no gold standard in diagnosis of this entity, and a multidisciplinary approach is necessary for proper diagnosis. Magnetic resonance imaging (MRI) is one of the most useful diagnostic modalities in early stages of CRPS (when clinical diagnosis is most difficult), the most desirable time to diagnose this disorder to expedite treatment and improve function. This article discusses MRI findings of CRPS, particularly in the early phase, and differential considerations.

However, CA is invasive and is associated with complications that result from the procedure itself, depending on the experience of the operators, site of vascular access, ionized radiation that could be significant when combined with interventional procedures, and administered contrast material. During the past 2 decades, technical improvements in computed tomography (CT) and magnetic resonance hardware and methods have contributed new, noninvasive tools, specifically CT angiography (CTA) and 3-dimensional gadolinium-enhanced magnetic resonance angiography (3D Gd-MRA). This article outlines the current applications, strengths, and weaknesses of CTA and 3D Gd-MRA in imaging of the mesenteric vessels.

To "tell the story" as accurately as possible, the radiologist must be familiar with the natural history of these lesions as well as distinctive imaging features and must take all relevant factors into consideration, such as patient's age, activity level, and surgical history. This article presents two cases to illustrate how imaging features affect the report and management plan. (Journal of Surgical Orthopaedic Advances.

This condition is a combination of rotator cuff tear, osteoarthritic changes, noninflammatory joint effusion containing crystals, synovial hyperplasia, cartilage and subchondral bone destruction, and multiple osteochondral loose bodies. This article discusses pathophysiology, clinical presentation, differential considerations, and magnetic resonance imaging findings of MSS.

This IRB-approved, HIPAA-compliant study had waiver of informed consent and retrospectively reviewed 50 patients (19 men, 31 women; mean age, 60 years) with negative prior and positive current CT findings for acute PE (median interval, 63 days). Interval increase was defined as percentage change in RV/LV diameter ratio by using reformatted four-chamber views. Receiver operating characteristic (ROC) analysis compared the interval increase with the RV/LV diameter ratio from the positive findings alone for PE-related and all-cause mortality. Twelve (24%) patients died in 30 days; nine were PE-related. The interval increase was significantly more accurate overall than the ratio from the positive study alone for PE-related (area under the ROC curve [AUC] = 0.95 vs 0.73, P = .003) and all-cause (AUC = 0.81 vs 0.66, P = .05) mortality. The respective sensitivity, specificity, positive predictive value, and negative predictive value were 0.78 (seven of nine; 95% confidence interval [CI]: 0.43, 1.00), 0.93 (38 of 41; 95% CI: 0.83, 1.00), 0.70 (seven of 10; 95% CI: 0.38, 1.00), and 0.95 (38 of 40; 95% CI: 0.87, 1.00) for PE-related mortality (interval increase, >18%) and 0.75 (nine of 12; 95% CI: 0.49, 1.00), 0.89 (34 of 38; 95% CI: 0.80, 0.99), 0.69 (nine of 13; 95% CI: 0.44, 0.95), and 0.92 (34 of 37; 95% CI: 0.83, 1.00) for all-cause mortality (interval increase, >15%). At target sensitivity (0.75), specificity of interval increase was significantly higher than from positive scans alone for both PE-related (0.93 vs 0.59, P = .001) and all-cause (0.89 vs 0.58, P = .05) mortality. The interval increase in four-chamber RV/LV diameter ratio is more accurate than the diameter ratio of the CT examination with with positive findings for PE alone for mortality prediction after acute PE.
